Spraying and squirting device



Patented Sept. 17, 1935 UNITED STATES PATENT OFFICE Application January 12, 1933, Serial No. 651,403

In Germany February 2, 1932 3 Claims.

This invention relates to a spraying and squirting device.

The known devices of this class comprise a container for the material to be dispersed and a top member with duct, which is detachably connected with the container. The duct has on one side an aperture while on its other side a bulb or an air pump is provided for producing overpressure in the container through the duct.

In the known devices cocks are used for closing which permit the simultaneous opening and closing of all conduits leading into the container. These closures suffer, however, from the drawback that they fail to be positively closed whenthe device is not in use or that they will release themselves by friction or the like when carried for instance in a handbag.

These drawbacks are fully eliminated by the invention according to which the cock closure is rigidly connected with the means for compressing air in such a way that the air compressing means, preferably constructed as bulb, closely hugs the container in closed position and is extended therefrom in opened position. The container is preferably provided with a depression for accommodating the bulb closely adjacent to the container in closed position of the device. Since the bulb, in the latter case, lies in the plane of the container and otherwise is spread out from the latter, the optical impression indicates whether the container is open or closed. This optical effect is supplemented by a mechanical one if the container is to be kept in fiat covers, hand-bags, vest pockets, etc., in which case the extended bulb is positively returned to closed position.

Another advantage afforded by the invention is that the device can be operated with one hand, owing to the rigid connection of closure and air pressure means. This feature is particularly important for pocket atomizers, as a woman for instance usually has to hold the handbag whence the atomizer has been taken during use. The invention provides therefore a practical, positively protected one-hand atomizer.

By way of example, the invention is illustrated in the accompanying drawing, in which Figure 1 is a side view of a pocket atomizer in closed position; Fig. 2, a front view thereof when in position for use; Fig. 3 shows on an enlarged scale the bordered free front end of the air supply duct; Fig. 4 shows a construction, in which in contrast to Figs. 1 and 2 the duct is not adjustable about its longitudinal axis but vertistruction, in which in the air supply duct, between the two apertures opening into the container, a partition is provided, the modification shown being particularly adapted for spraying powders.

Referring to the drawing, a top member 2 is detachably secured to the container l which, according to Figs. 1 and 2, is threaded to hold the threaded top member 2. The top member 2 has a bore 4 for receiving a duct 3. Two bores 5 and 6 extend into the inside of the container l. The free endof the duct 3 forms a nozzle 8, and the rear end is connected by the member 9 w th the air pressure means formed as a bulb.

In the duct 3 two openings II and 12 are ar- 15 ranged so that they are displaced 90 relative to the bores 5 and 6 in the position shown in Fig.

1 while .n the position shown in Fig. 2 the bores H, I2 and 5, 6 open into one another.

The bore 1 of the duct is reduced betweenthe openings II and I 2 to vary the speed of the air flowing through it. The suction effect thus created is transmitted through the bore 6 and the pipe l5 to the contents of the container.

The front end of the duct forms a collar, Fig. 3, to prevent the tube from falling out. The duct 3 is rotatable about its longitudinal axis in the top member 2, the rotary motion being laterally limited by a pin l3 secured to the duct and movable in a segment-like recess of the member 2.30 The container I possesses a depression to facilitate hugging of the bulb in closed position.

Fig. 5 shows a modified construction of the atomizer, in which the duct 3 is interrupted between the two bores 5 and 6 by a partition I! to provide for the complete introduction of the air supplied by the air pressure means into the container and to insure the driving out of the contents thereof through the second aperture, the duct and nozzle. The bore 1 is not reduced 4 towards the free end so as not to interfere with the discharge of the material to be dispersed. This type of atomizer is suited particularly for squirting powders. To loosen up the material to be sprayed a tube 23 is connected to the aperture 5.

If, on the other hand, the contents of the container are to be discharged through the nozzle in fine distribution, a duct without a partition is used according to Figs. 1 and 2 in order to cause a part of the air to enter the duct directly and aspirate the contents in injector-like fashion.

Fg. 4 shows a second modified construction. In the container l a lower top member 25 is detachably connected with the container to which the upper top member 21 representing a special form of an air supply duct is rotatably secured by suitable means, such as a screw 16. To insure good packing the face 28 between the two parts may be conical. The-bores 28 and 30 of the duct 3! are continued in corresponding bores 32 and 33 of the lower member 25 and are closed or opened by the turning of the upper member 21. In this second construction the duct is rotated about an axis extending vertically to the center line of the duct.

I claim:

1. A spraying device comprising a container, a top member detachably secured to said container and closing it, a horizontal atomizing tube having one end extending rotatably through a portion of said top member, two bores in said top member leading from said tube to the container, said atomizing tube having two lateral openings in said one end and an air pressure generating member connected laterally to the other end 01' said atomizing tube, said air pressure member being rigidly connected therewith, said openings being so located as to establish communication between the interior of the atomizing tube and said bores when the air pressure member is rotated to a position extending laterally oi the container, and to close oil such communication when the pressure member extends downwardly.

2. A device according to claim 1 constructed as pocket atomizer, in which the container has a depression, said depression being engaged by the air pressure member when that member extends downwardly.

3. A device according to claim 1, in which the top member has a segment like recess and a pin is provided on the atomizing tube, said recess serving as stop for said pin.
